Notes on Quality

Cheese: Freshly grated melts better and adds more flavor bagged cheese contains anti-caking agents that can affect texture.
Tater tots: No need to thaw frozen tots hold up better in baking and crisp nicely on top.

Possible Substitutions

Step-by-Step Instructions

Step 1: Preheat & Prep
Preheat your oven to 350°F and spray a 9"x13" baking dish with nonstick spray. Set aside.

Step 2: Cook the Sausage Mixture
In a large skillet over medium-high heat, cook the sausage with diced onions and bell peppers. Crumble the sausage as it cooks. Once it's browned and the veggies are soft, stir in the garlic and sauté for 30 seconds. Drain any excess grease.

Step 3: Layer the Base
Transfer the sausage mixture to the prepared baking dish and let it cool slightly.

Step 4: Whisk the Egg Mixture
In a large bowl or measuring cup, whisk together the eggs, half-and-half, green chilies, and all seasonings. Set aside.

Step 5: Assemble the Casserole
Add half of the tater tots to the sausage in the baking dish along with ¾ cup each of cheddar and pepper Jack cheeses. Gently stir to combine and spread into an even layer.

Step 6: Add Eggs & Top with Tots
Pour the egg mixture evenly over the sausage-tater tot mix. Then, scatter the remaining tater tots across the top in a single layer.

Step 7: Bake
Bake uncovered for 70-80 minutes, or until the eggs are set in the center.

Step 8: Final Cheese Layer
Remove from oven and sprinkle with the remaining cheese. Return to the oven for 5-10 more minutes until melted and golden.

Step 9: Serve
Let the casserole rest for a few minutes. Top with fresh chopped chives or green onions if desired. Then slice, serve, and soak up the praise.
